26.1.4 Listener area

The
Listener
tab provides a Listener in which the execution steps are indicated. Commands can be entered here as an alternative to using the buttons on the Stepper toolbar.

Any form entered here is evaluated on the dynamic environment of the function being stepped.

Moreover, you can use the debugger commands such as
:v
, which prints the local variables in the current frame. You can use the value of a local variable simply by entering its name as shown. See the
LispWorks User Guide and Reference Manual
for more details about the debugger commands.
